BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to mobile phone accessories. Specifically, and not by way of limitation, the present invention relates to a grip attachment providing camera control of a mobile phone.

2. Description of the Related Art

With the advent of digital cameras, photography has become more popular than ever. Digital cameras enable users to take and store many photographs. Because of their compact size, digital cameras are easy to carry, thereby allowing many people to always have quick access to their cameras. However, as popular as digital cameras have become, mobile phones with their highly capable camera functions, have literally changed photography in a completely different way. These camera phones are capable of taking high resolution photos and incorporate many photographic features found on most digital cameras. Touch screen telephones are particular popular whereby a user interfaces with the camera by using the touch screen. However, these touch screen camera phones suffer from several disadvantages. First, a user cannot easily hold a phone with just one hand when taking photographs or video segments. With touch screen phones, a user must use both hands where the user's first hand holds the camera while the user's second hand manipulates the camera functions by touching the touch screen. This is a very cumbersome process where a user typically uses both hands to take a photograph. Many traditional cameras, prior to mobile camera phones, often used a hand grip located on one side of the main body of the camera. Oftentimes, the hand grip incorporated a shutter release on the hand grip which enabled a user to grasp and take a photograph with just one hand. It would be advantageous to have an apparatus which enables a user to conveniently take a photograph or video from a mobile phone with just one hand.

There are existing phone cases which enable a user to take a photograph by depressing a button on the case. However, none of these existing cases enables a user to easily grasp the camera body and take a photograph with just one hand.

It would be advantageous to have a hand grip adapter which is easily attached to a mobile phone and enables a user to manipulate the camera functions from the hand grip without touching the touch screen. It is the object of the present invention to provide such an apparatus.

SUMMARY OF THE INVENTION

The present invention provides a grip attachment for a mobile phone which enables a user to grasps and control a camera of the mobile phone with one hand. In one embodiment, the present invention is directed to a grip attachment for a mobile phone. The grip attachment includes a main body and an enlarged grip extension attached to a first end of the main body. The enlarged grip extension is sized and shaped to enable a user's hand to hold the grip extension and attached mobile phone with one hand. The grip attachment also includes a locking mechanism for attaching the attachment grip to a portion of a mobile phone protective case. A second end of the grip extension includes a connector for interfacing with a connector of the mobile phone. The grip extension includes an external control located on an outer surface of the grip attachment for activating a camera control of the mobile phone. The external control may interface with the mobile phone by utilizing a pin connector interface, a Bluetooth interface, sound module, Infrared Interface, or any other interface allowing the grip attachment to utilize a camera control of the mobile phone.
